ubuntu 10.12’s unity 3d desktop performes rather slow on my QuadCore Xeon OSX 10.6.8, so i thought i try to improve performance by properly installing the guest additions:

open a terminal in ubuntu:

1. optional, but i recommend it because copy & pasting commands is just much more comfortable than typo’s: install ssh server:

apt-get install ssh

ifconfig

-> look for 192.168…. this is your ip

now open a terminal on the unix-compatible-host: ssh user@192.168….

2. get linux kernel headers (sources?)

apt-get install linux-headers-3.5.0-25-generic

3. download guest additions

sudo apt-get install virtualbox-guest-additions-iso

4. mount iso

sudo mount -o loop /usr/share/virtualbox/VBoxGuestAdditions.iso /media/cdrom0

5. install guest additions

sudo /media/developer/VBOXADDITIONS_4.2.10_84104/VBoxLinuxAdditions.run

you should see something like this:
Verifying archive integrity… All good.
Uncompressing VirtualBox 4.2.10 Guest Additions for Linux……….
VirtualBox Guest Additions installer
Removing installed version 4.2.10 of VirtualBox Guest Additions…
Removing existing VirtualBox DKMS kernel modules …done.

Doing non-kernel setup of the Guest Additions …done.
Starting the VirtualBox Guest Additions …done.

the guest system) to enable the Guest Additions.

Installing graphics libraries and desktop services components …done.
